To aZZw/iom t may concern." Be it known that I, HARRY" WALKER a tain new and useful improvements in Semaphores, of which the following is a specification, reference being had therein to the accompanying drawing.`

This invention relates to vsemaphore sig-y nals used upon automobiles and the like, and has for its object the production of Ia` simple and efficient semaphore which may be very cheaply manufactured. and eiiciently` signal to return t'o its inoperative position, through the force of gravity.

W ith these and other objects in View, this invention consists of certain novel combinations, constructions, and arrangements of parte will be hereinafter fully described and claimed^ y ln the accompanying drawings: Figure 1 is a elevation of an automobile, showing the attachment 'of the semaphore signal Fig. 2 is a rear elevation of an automobile, showing the semaphore attached thereto. Fig.` 3 is a central vertical section through the semaphore. Fig. 4 is an edge view of the semaphore casing. Fig. 5 is a vertical section through the semaphore arm. Fig. 6 is a section taken on line 6-6 of Fig. 5. Fig. 'Z is a section taken on line 7 7 of- Fig. 3, sho-wing the bell imposition. Fig. 8 is a section taken on line 8,-8 of Fig. 5. Fig. 9 is a perspective view of the semaphore operating arm. Fig. 10 is a section taken on the line X-X of Fig. 3. Fig. 11 is a section taken on line Y-Y of Fig. 2.

lt should be understood that the semaphore casing may besupported inany desired or convenient manner upon the automobile or vehicle such., for instance, as to the rear of the vehicle, or to the wind shield thereof, and in fact in any desired position found convenient to the operator of the machine.

Referring to the accompanying drawings by numerals, it will be seen that 1 designates the semaphore casing which is provided upon the rear face thereof with a mirror 2,

11 formedtherein which apertures are preferably covered with red color sheets 12 behind which sheets is mounted an electric bulb 13, supported upon a metal bracket 14. One terminal of the bulb 13 is grounded upon the bracket 14 by means of a wire 15 and the other terminal of the bulb 13 connects with a conducting wire 16, which conducting vvire is clamped in engagement with one of the plates 4 by meansI of the bracket 17. This wire 16 is connected to one of the terminals 19, which terminal 19 is connected to any 4suitable source of electrical supply which electrical supply is connected to the binding post 20. It of course should be understood that this electrical supply means is grounded upon the semaphore arm 5 in any suitable lor desired manner to complete the electrical circuit through the bulb 13 when a suitable circuit closer is operated for closing the electrical circuit through the Wire 16. It is thought unnecessary to go into the detailed construction of the circuit closer and electrical mechanism as the electrical connections of the device will be obvious.

A pair of electromagnets 21 are placed within the casing 1 and these electromagnets are electrically connected to a wire 22 as are also the magnets 9, the wire 22 being connected to avbinding post 23, which binding post 23 is connected to any suitable electrical supply source. The ground wire 24 is connectedv toa connecting bolt 25 which is mounted upon the clamping bracket 26 for permitting one terminal or conductor for .Miete A* .and in fact the entir?A mehangm' .ofy Veryjm.

both the lighting and operating circuit. This electrical connection is obvious to anyone skilled in the ait. An armature 27 is pivotally supported upon 4a bracket 28 and an angle {iange 29 is secured to the arm 27 for constituting a. means for engaging an electrical magnet 21. A hook 3() is formed upon the upper end of the arm 27 and a- -chain 31 is connected tothe upper end of thearni 2T and is also keyed or connected to the drain 3 for permitting the swingingof. the semaphore arm 5 to the position shown in dotted lines in Fig. 3 when the arm 27 is attracted by the magnets 21. p

The casing 1 is provided with a nipple plate 32 in which nipple plate is threaded a pipe Vsection 33 engaging a clamp This clamp 34 comprises a pair of sections held together by means of the bolts for firmly causing the clamp to be down around a supporting rod 35, as illustrated in Fig. 2.

From the foregoing description it will be seen that a very simple and efficient means has been produced for actuating the sema' phore arm 5, whereby a signal will be given to a person inthe rear of the automobile carrying the signal and audible alarm will also be sounded to call the attention of -the person following the car to the fact that a signal is given indicating the direction of turn of the automobile or machine carrying the signal.

It 'should be further understoodv that a very simple and eilicient construction has been produced comprising a minimum number of parts, wherein the parts used are formed of the lightest material possible and at-the saine time held in a very rigid position for efficient operation.

What I 'claim is A signal of the class described comprising a casing, a semaphore arm, said semaphore ar in comprising a pair of similarly constructed plates, a channel plate connecting said plates and extending along one side of said'arm for reinforcing said plates, a drum carried by said semaphore arm, an

`armature lever, means for attracting said armature lever, and flexible means connected to said drum and armature lever for swinging said semaphore arm.

In testimony whereof I hereunto ahx my signature.
